  • Patent number: 12168994
    Abstract: This application provides a rotating mechanism, a support apparatus, and a terminal with a foldable screen. A problem that a rotating part with a large volume affects lightening and thinning of an existing terminal with a foldable screen is resolved. A transmission assembly is in a transmission connection to a first swing arm and a second swing arm, so that the first swing arm and the second swing arm rotate between a folded position and an unfolded position. When the first swing arm and the second swing arm rotate from the folded position to the unfolded position, a connection plate moves in a direction away from the shaft cover, and when the first swing arm and the second swing arm rotate from the unfolded position to the folded position, the connection plate moves in a direction close to the shaft cover.
